High impact information on Colubrina

  • Unexpectedly, however, the glands of Laticauda colubrina and Russell's viper include a large quantity of antihemorrhagic factor and inhibitor of PLA2, respectively, that have been previously described in snake plasma [1].
  • On the other hand, competition binding with tritium-labeled toxin alpha to Narke japonica acetylcholine receptor has revealed that cleavage of the C-terminal residues reduces the binding activity of alpha-bungarotoxin or Laticauda colubrina b to acetylcholine receptor [2].
  • Similarly, from the venom of a population of L. colubrina from the Philippines, a neurotoxic component, Laticauda colubrina b (toxin Lc b), was obtained in 10.0% (A280) yield [3].
  • Lipoxygenase inhibition by anadanthoflavone, a new flavonoid from the aerial parts of Anadenanthera colubrina [4].
  • The immunomodulatory and anti-tumoral effects of an acidic heteropolysaccharide containing mainly galactose and arabinose (ARAGAL), isolated from the gum of the leguminous tree Anadenanthera colubrina (Angico branco) native to Brazil, were studied [5].

Anatomical context of Colubrina

  • A novel method is described for the determination of sequential side-chain structures in the complex, high-arabinose polysaccharide of the gum exudate of angico branco (Anadenanthera colubrina), using as basis the structurally similar reducing oligosaccharides present in small quantities [6].

Associations of Colubrina with chemical compounds

  • Mabiosides C-E: triterpenoid saponins from the bark of Colubrina elliptica [7].
  • Three new jujubogenin glycosides, namely, 3' '-O-acetylcolubrin (1); 3' ',2' "-O-diacetylcolubrin (2), and 3' '-O-acetyl-6' '-O-trans-crotonylcolubrin (3), were isolated from the leaves of Colubrina asiatica, in addition to the known colubrin, rutin, and kaempferol 3-O-rutinoside [8].
